Sorry for my late reply nanasess,

I just find some problem of this Paypal Plugin, as our EC-Cube 4.0.3 will change to use English language. Once we change to English, this Paypal problem will occur.

When we change back to Japanese, the Paypal plugin also has this issues and paypal plugin cannot work anymore.

PS: we have installed a new Ec-cube 4.0.3 at new virtaul machine to test.

Thanks and Regards,

Roy Leung

PayPal API error is output in Japanese.

"エラーの詳細についてPayPalカスタマーサポートにお問い合わせください"
translate to
"Please contact PayPal Customer Support for error details."

Details of the error is such that only the customer support to know.
Please contact to PayPal customer support.

Thanks for your information. I have tried to add the paypal.debug

However, it still not success. The log display the following.

Please try to add this code to "app/Plugin/PayPalCheckOut/Resource/config/services.yaml" in parameters section.

I am not sure about where is the parameter of "paypal.debug"

Look for "システムエラーが発生しました" record in /path/to/ec-cube/var/log/xxx/site-yyyy-mm-dd.log

Display to this error message when you check out with PayPal?

Dear Kentaro San,

Yes, the Paypal configuration is completed at Admin / Plugin and input Client ID and Secret already.

Just wonder if there is any system setting i am missing.
